Also other are other units.
So, in the metric system to measure the volume of solids popular cubic centimeters, cubic decimeters, for liquids, liter, milliliter, for bulk products, a tea spoon, glass (though they are usually measured by weight).

The volume denoted by the letter V.
To calculate the volume of geometric shapes use mathematical formulas. for Example, the volume of a cube can be calculated as V = a³. - where "a" being length of one side of cube.

Also we can calculate a density (p) of bodies by dividing the mass by the density: V = m/p.

For bodies that not absorbing the water, you can use displacement.
For example, watermelon is placed into a graduated container, which is already some amount of of water (for example 2 liter). After placing watermelon into water we measure how the water level rose. The difference of water levels in the vessel before the watermelon and after of the watermelon will be the volume of watermelon.
